Alex studies the complex social and collective systems of animals great and small – the ways single individuals come together to form much larger groups, and the feedback between the behaviour of groups and that of the individuals that compose them. His research program encompasses field studies in Africa, Australia, and the Americas, and lab approaches including molecular genetics, neurobiology of social interactions, and socio-cognitive behavioural assays. His group aims to understand both the proximate mechanisms and the ultimate outcomes of social interactions and behavioural plasticty. His research group page is here
My research involves integrating neurobiology, development, evolution, and behavior to understand the proximate and ultimate causes behind sociality in birds. During my PhD at Cornell University, I studied the role the nonapeptides (oxytocin, vasopressin, and their non-mammalian homologues) play in regulating parental care and maintaining pair bonds in zebra finches. I also determined that corticosterone plays no role in regulating helping behavior in cooperatively breeding Mexican jays. I have also studied how sociality influences numerical cognition in Mexican jays and Woodhouse’s scrub jays. In the Couzin lab, I am collaborating with the imaging barn group to studying how hormones regulate individual and group flocking decisions in quail. These experiments will employ the state of the art 3D acoustic tracking system developed by the lab to track every individual quail’s movements and vocal communication in a semi-natural environment.
Aya Goldshtein conducted her Ph.D. at Tel-Aviv University where she studied foraging decision-making and navigation capacities in bats. During her research she studied the mutual relationship between nectar-feeding bats and their food source, the Saguaro cacti, revealing the foraging strategy and the decision process bats deal with while consuming the cacti’s nectar. She is now interested in expanding these questions and unravels the foraging strategy and the decision process of hummingbird hawk-moth.

Christina is a behavioural ecologist interested in behavioural evolution, and how fitness is modulated by the interplay between behaviour and various biotic and abiotic factors. She received her PhD from Stockholm University, Sweden, working with wolves and dogs to answer questions about how behaviour has evolved during domestication—specifically demonstrating how domestication can break behavioural correlations. In 2020, Christina was awarded a three-year postdoctoral fellowship by the Swedish Research Council to come work at the Farine Lab, where she will explore how group-living affects individual physiology and fitness in vulturine guineafowl. For her project she will combine high-resolution bio-logging data from GPS and ECG tags to quantify fine-scale physiological responses to spatial positioning within a social group. She will then extend this with experimental manipulations to investigate how these responses are mediated by individual-level traits and environmental factors, such as predator response and social status. Read more on Christina’s website.
Daniel has a background in physics but over the years studied many types of collectives at multiple levels (amoebae, fish, lymphocytes and termites). His approach to studying these complex systems is through a combination of quantitative experiments and computational methods to analyse experimental data. From proposing relevant experiments to the analyses that uncover the mechanisms behind the complex features animals and cells display, leading to computer simulations which reproduce and test the limits of the proposed mathematical description.
David is a behavioural ecologist interested in the behavioural adjustments of individuals in responses to environmental changes, especially changes in temperature and water availability. At a broader scale, his aim is to understand how animal behaviour could buffer the local effects of global change and ultimately to predict individuals’ activity window under different climate change scenarios. David received his PhD in 2019 from Sorbonne Université in Paris, during which he described and studied thermo-hydroregulation behaviours in the common lizard in response to variable temperature, water presence and moisture conditions. In 2020, David was awarded an Alexander von Humboldt Postdoctoral Fellowship to join the Vulturine Guineafowl Project in the Farine Lab. His project focuses on describing how thermal conditions and overheating risk influences activity patterns, movement decision-making processes and foraging probability of individuals during dry seasons, when resources are scarce and segregated. He will also have a particular interest in highlighting how group-living influences the costs-benefits ratio of behaviours in these high constraints environments. One of his main task is to map the heat constraints landscape to predict the local overheating risk and shade availability across the day in groups’ home ranges. Ultimately, his research could give insights on the consequences of global changes on this population of vulturine guineafowl.
Eli is a behavioral ecologist interested in the ecological and evolutionary forces underlying group living, with a focus on social hierarchies and the role they play in the broader context of the costs and benefits of sociality. Eli received his PhD in 2019 from Michigan State University, where he studied social dynamics in the complex, hierarchical societies of wild spotted hyenas. In his ongoing work, he is pursuing comparative research into basic principles underlying the ubiquity of inequality and social hierarchies across taxa. Eli also continues to work with the Mara Hyena Project to explore the processes that produce long-term patterns in social behavior, demography, and reproduction. In addition to questions about social biology, he is passionate about advancing quantitative methods for analyzing social data, and about the importance of mentorship in academia. Eli joins the lab as an Alexander von Humboldt Postdoctoral Fellow studying the ontogeny of dominance and other social traits, using vulturine guineafowl and spotted hyenas as systems in which to explore divergent pathways of social development.
I have been fascinated by insects, especially ants, since my early childhood and have spent countless hours observing them in the wild and later also in the laboratory. During my masters, I worked on ants living in an intricate symbiosis with an ant-plant in Costa Rica. Since then, I have mostly worked with social insects, from road construction in meat ants to olfactory conditioning in honeybees. During my PhD, I investigated how cognitive abilities of ants can drive individual or collective decisions. Here in Konstanz, I investigate collective sensing in groups of desert locusts. Using individual tracking, I try to understand and to reconstruct how information spreads through the group and how individual decisions affect the system. Moreover, I will also investigate foraging dynamics of ant colonies to better understand how insect groups organise themselves.
Hanja is a behavioural ecologist exploring the effects of stress on social behaviour, pair-bonding, and group function in zebra finches.

Mauricio Cantor is a Brazilian biologist who is interested in behavioural ecology and the ecology of interactions both among species and individuals. His research focusses on the emergence of patterns and strategies in non-human animal societies, mainly using whales and dolphins as models due to their behavioural plasticity and social system complexity—as well as exciting fieldwork challenges. Mauricio recently joined the Farine lab at the Max Planck Institute for Ornithology to develop his postdoctoral research on the evolution of interspecific cooperation, specifically the cooperation between top predators to access a common resource. In using state-of-the-art computational tools and mathematical models to confront unprecedented empirical data on the unique cooperative foraging between wild dolphins and artisanal fishermen from southern Brazil, Mauricio will quantitatively evaluate the direct benefits accrued from both predators aiming to unravel the mechanisms generating such unique cooperation between human and wildlife. Mauricio is also involved in some spin-off research projects, most of which adopting network thinking to explore processes at the population (e.g. social behaviour among terrestrial and aquatic vertebrates) and community levels (e.g. ecological interactions and interspecific behaviour).

He is a Humboldt Fellow and was previously a Smithsonian Postdoctoral Fellow at the Smithsonian Tropical Research Institute and a Ford Predoctoral Fellow at the University of Maryland. Gerry is working to develop food-sharing vampire bats as a tractable experimental model for studying how individuals choose and regulate cooperative relationships. He is currently analyzing data from a 22-month experiment with vampire bats that (1) measured how food sharing developed between previous strangers housed together in captivity, (2) manipulated new and old relationships by changing partner behavior, and (3) tracked roosting and foraging association in the same bats released back into the wild. Gerry is now an Assistant Professor at The Ohio State University – see https://socialbat.org.
I’m a biologist from Switzerland, and I work on coral reef fish behaviour. I completed my PhD at the University of Neuchâtel (Switzerland) on the behaviour of the bluestreak cleaner wrasse Labroides dimidiatus with Prof. Redouan Bshary. I am now at the Max Planck Institute in Konstanz (Germany) doing a project on the collective behaviour of damselfish with Prof. Iain Couzin & Dr. Alex Jordan.
Matt is a fourth-year PhD candidate in Ecology and Evolutionary Biology at Princeton. He studies how the perception of risk affects information transfer through fish schools. As an undergraduate at the University of Illinois, Matt researched the relative importance of different antipredator benefits of shoaling in threespine stickleback. He then spent a year in Seewiesen, Germany studying sleep and social foraging in great tits at the Max Planck Institute for Ornithology, funded by a Fulbright grant. On the side, Matt keeps a blog on biology, academia, and metal music: mattgrobis.blogspot.com.
Olivia is a PhD candidate at Princeton University. She is a member of both the Collective Behavior Lab, where she is advised by Dr. Iain Couzin, and the Social Learning Lab, which is directed by Dr. Daniel Rubenstein.
In her work, she applies an interdisciplinary approach to researching questions that focus on how environmental manipulations, such as social setting or the difficulty of a foraging task, affect animal movement and decision making behaviors during naturalistic search. To address these questions, she uses human visual search as a toy-model system, employing eye-tracking technology to record the location of gaze and attention during visual search tasks across a variety of social and environmental conditions. Her main goal is to produce a body of work that will be broadly informative to studies of animal movement and decision making. However, she is also interested in applying her work to the field of medical imaging, with the specific intention of determining whether or not social information in the form of shared-gaze could reduce the rate of false negative diagnoses and be a useful intervention for radiologists. Her personal website can be found here.

Ian is a computational ethologist interested in understanding the relationship between perception, behaviour and social organisation. During his PhD, he is exploring the role of these dynamics in mate choice, extended cognition and group competition. He asks how animals actively shape their perception of the environment, the perception of themselves by others and the effect of the social context on these processes.
Jana is a undergraduate at the University of Konstanz. She started studying Biological Science in 2013. Because she discovered her fascination for ethology, conducted her Bachelor thesis in the Farine Lab. She studied the role of individuals in collective problem solving in zebra finch flocks. Her research included investigating leadership in zebra finches flocks and finding out whether leadership is important for producing informations within the flock. Jana is now doing her Master’s thesis in the Aplin lab, testing whether cockatoos can individually recognise humans.
John Ewoi has been working at the Mpala Research Centre for over 10 years and has collaborated on numerous projects. Examples include sampling mosquitos for research into malaria, photographing the distinct flank stripes on Grevy zebra to identify individuals, and trapping spider mice in cliffy habitats. His main area of research assisting, however, has been focussed on the Grant’s gazelles for the last 7 years. This involved collecting behavioural data in the field, ear-tagging gazelles, tracking collared gazelles using telemetry and doing lab-based faecal parasite counts. Presently, he has joined the Vulturine Guineafowl Project research group, where his vast experience in the bush has been truly indispensable. The GPS-data is what excites John the most as it will give a unique insight into where these birds roam when no one is watching…
Jolle Jolles is a Dutch Behavioural Ecologist who is fascinated by how animals live in groups. His research focuses on the role of consistent individual behavioural differences (animal personalities) in collective behaviour. Jolle recently completed his PhD at the University of Cambridge with Dr. Andrea Manica where he studied the interplay between personality differences and the social context in Three-spined sticklebacks. In March Jolle joined the Couzin lab at the Max Planck Institute for Ornithology in Konstanz. He uses state-of the art individual-based tracking techniques to study how individual differences affect the collective movements, decision-making and group performance of large, dynamic schools of fish, both in the lab and under semi-wild conditions.

When asked what I do for a living, my usual answer is “I clean up jellyfish poop,” which is partially true. But that’s really just a means to a more interesting end: studying (marine) organisms, their behavior, and their interactions with the physical environment.
For the past few years, I have studied the fluid dynamics of pulsing behavior in xeniid corals. These soft corals generate fluid flows that influence local nutrient and gas exchange. For my current research project, I try to figure out whether there is a pattern to the collective pulsing behavior, what influences this behavior, and how differences in the collective pulsing (for example different timings or pulse frequencies) affect local flow fields.
My background is in biology, with a tendency towards biomechanics and mathematical modeling of biological systems. Where possible, I like to integrate different approaches to a biological question by combining experimental work, modeling, and fieldwork. I also strive to look for solutions outside of my field through collaborations with mathematicians and engineers, among others. The more pieces we have, the better we can solve the puzzle!

Matthew is a biologist and architect. His work across disciplines is driven by a desire to understand how simple rules and interactions between individuals give rise to complex pattern and structure at higher levels of organization. He completed his PhD in Ecology and Evolutionary Biology at Princeton in 2016 with Iain Couzin, where the focus of his dissertation was the self-assembled structures built by army ants of the genus Eciton out of their own bodies. He conducted field experiments in Panama to understand the dynamics of these structures and their adaptive benefits at the colony level. Prior to this, he received an MS in Advanced Architectural Design from Columbia University, where he focused on developing computational methods of generative design inspired by the self-organizing principles of collective animal behaviour. As a Postdoctoral Fellow in the Jordan Lab, Matthew is researching the interactions between building behaviour, web structure and group living in social spiders.

He pursued his PhD with Juan Carlos Senar in Barcelona, where he studied social and sexual functions of colour traits. After completing his dissertation, he joined Mats Björklund and Fredrik Sundström in Uppsala, where he worked on the evolution of species interactions under fluctuating environmental conditions. Fernando has been subjected to fluctuating conditions himself by further exploring his research interests in field trips around Europe, Africa, the Americas, and Australia. He is now working in the Jordan lab on the evolution of social influence in the social cichlid Neolamprologus multifasciatus.
I am an empirical biologist, with a strong interest in social behavior within groups of animals. In particular, I aims to get a better understanding of information transfer and collective decision-making in groups of fish. On a broader context, I am also very interested in individual differences within populations (e.g. personality traits), how social units are structured in nature, predator-prey interaction as well as theory of games and sexual selection. Even though I am keen to work on any model species, I tend to be fascinated by fish behaviour. I earned a Master Degree in Behavioural Ecology from the Université de Bourgogne (Dijon, France).
Position: research assistant
Melanie is studying how the structure of social groups affects information flow and influence networks in communities of Lamprologine cichlids.
Previously he was a Royal Society Newton Fellow in the Department of Zoology, University of Oxford and Junior Research Fellow at Somerville College, Oxford working with Dr. Dora Biro. He has been a post-doc and he did his PhD in Physics at Eötvös University, Budapest with Professor Tamás Vicsek, studying collective motion and leader-follower relations in pigeon flocks and modelling self-propelled particles.
I am a behavioural ecologist who is interested in how different species use acoustic communication during social or collective behaviours. Many animals are incredibly vocal and may rely heavily on acoustic communication to coordinate group behaviours such as mobbing (harassing a predator to drive it from the area) and moving through their environment. My postdoctoral research is focused on how birds use vocal and visual information to coordinate group movement and maintain flock cohesion in a variety of environments. For this project I will be collaborating with other group members to employ a 3D acoustic tracking system to allow us to track both movements and vocal behaviour of all individuals in a flock as they travel through a semi-natural environment. During my PhD at the University of St Andrews, my research has focused on mobbing behaivour in tit species, how different tit species include information about a predator’s level of threat in their mobbing calls, and how this information is used by the wider avian community. More recently, during a postdoc through the university of Porto, Portugal, I conducted experiments to examine some of the underlying drivers for cooperative behaviour in sociable weavers, a small communal breeding passerine found in Southern Africa.

Sofia studies animal communication and the evolutionary processes underlying mate choice and social interactions. She recently completed her PhD with Prof Mike Ryan at UT Austin, looking at the interaction between acoustic signalling and chytrid infection in Tungara frogs. As a postdoc in the Jordan lab, she is studying how seismic communication is used by social spiders to coordinate group movements, and how the structure and connectivity of webs influence signal transmission.
Vivek is an Evolutionary Biologist interested in the interplay between individual and group level properties in animal societies. More specifically, how selection operating on decision rules adopted by individuals affects collective motion, environmental sensing, information propagation and decision making in animal societies and how these group level properties in turn affect individual fitness. He wishes to explore these ideas from both a mechanistic and functional perspective using both theory and experiments. Otherwise, Vivek enjoys sports and being outdoors in general.
Sylvester Karimi, locally known as Stalone, has worked with the Ornithology section in the Zoology department of the National Museum of Kenya for the last 16 years. Here he has assisted on avian flu surveillance, annual water fowl census and migration ringing in Tsavo National Park. Lending his expertise to short-term projects has taken him around the country: GPS collaring endemic Aberdare cisticolas in the Aberdare ranges, telemetry tracking the endangered Taita thrush in the Taita hills, ringing Papyrus gonolek by Lake Victoria and surveying Kori bustards in Marsabit. His ornithological work has also taken him on international expeditions along Israeli migration routes, Hungary with the Earthwatch and Taiwan for behavioural observation work, to name but a few! He has been dividing his time between Nairobi and Mpala Research Centre for the last four years. Although it was the grey-capped social weavers that brought him here, he then spent 18 months as a full-time member of the Vulturine Guineafowl Project.
